portland cement

I'm a little stuck... Click here to teach me more about this clue!

'a setter?' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.

'condemn prattle that's involved' is the wordplay.
'that's involved' indicates anagramming the letters (involved can mean confusing or complex).
'condemn'+'prattle'='condemnprattle'
'condemnprattle' with letters rearranged gives 'PORTLAND CEMENT'.

Can you help me to learn more?

(Other definitions for portland cement that I've seen before include "Material for building" , "Bond" , "hard stuff!" .)
